SPECIFICATION forming part of Letters Patent No. 621,784, dated March 28, 1899.

Application filed October 18, 1898. Serial No. 693,913. (No model.)

To all whom it may concern.-

Be it known that I, PIERRE BARDQT, a citizen of the Republic of France, residing at .Lyons, France, have invented certain new and useful Improvements in Means for Lighting Incandescing or other Gas-Burners- Provided or not withOhimneys, of which the following is a full, clear, and exact description.

The present invention relates to the lighting of gas lamps or lanterns provided with incandescing burners of the Welsbach or other system. These lamps or lanterns at present require from the lamplighter rather complicated operations, which frequently result in the breakage of the mantles, and they can only be lighted by means of spirit-lamps, which are readily extinguished by the wind, and necessitate two different lighting systems in districts provided with both the ordinary burners and the incandescing burners.

The invention consists in an arrangement which by means of an ordinary oil-lighter and by a simple action enables all the operations required by this lighting to be readily and automatically accomplished.

' The invention is represented in the accompanying drawings, in which Figure 1 is a front view, and Fig. 2 a side view, of the apparatus; and Figs. 3 to 5 are detail views showing different positions of the parts during the lighting and extinguishing operations.

The lamp or lantern is closed below by two panes of glass A A, one of which is hinged to permit of the lighting, which is effected by means of an ascending gas-conducting tube B, forming the lighting means, the jets of which are successively ignited up to the terminal nib, which in its turn ignites the Bun sen burner O.

The mode of operation is as follows: First,

the glass pane A is opened; second, the gas is caused to pass to the conducting-tube B; third, the gas issuing from the jet-holes in the tube 13 is ignited; fourth, the gas is caused to pass to the burner O; fifth, the light from the conducting-tube B is extinguished when it has lighted the Bunsen burner, and, sixth, the glass pane A is closed. These six operations, not one of which should be omitted, are successively and necessarily accomplished in the proper order by means of the following mechanism The gas-cockD at the foot of the lamp or lantern is operated by the lever E, which is of sufficient length to be conveniently reached by the lamplighters rod. This cock on its other side carries a lever F, which by a link G is connected to the movable pane A. The cock and its plug are provided with three ways or passages and arranged as shown at Figs. 3, 4, 5.

When the burner is extinguished, (see Figs. 1 and 3,) the levers E and F are horizontal and the pane A is closed. For the lighting the lever E is depressed by the lamplighters rod, so as to cause it to make about a quarter-revolution. The cock then assumes the position represented at Fig. 4 and the gas flows into the conducting-tube B and into the burner C. At the same time the lever F 'is in a vertical position and has raised the pane A. The lamplighter can then introduce his lamp into the interior of, the lamp or lantern and light the gas issuing from the c0nducting-tube,which immediately lights the burner. When this is done, the lamplighter again acts on the lever E, giving it a quarter-turn, and thus raising it to the horizontal position shown at Fig. 5. This movement effects the extinction of the light from the conductingtube. At the same time .the lever F becoming horizontal allows the pane A to close and the lamp or lantern is in the desired conditions for illumination; The extinction is effected bya single action by moving the lever F from left to right, thus replacing all in the position shown at Figs. 1 and 3.

It will be seen that without requiring any special precaution in lighting the requiredfrom the tube B is capable of regulation by means of the pointed screw V.

(See Figs. 3, 4, and 5.)

. Having thus fully described my invention,

loo

a positive connection with the pane so that the operation of the cock will move the pane, and means for operating the cock so that the pane will be opened when the cock is open in one position and closed when the cock is open in another position, substantially as described. A

2. In combination, the lamp having the movable pane, the three-Way cock having a connection to the pane and means 'for operating the cock so that the pane will be opened when the cock is open in one position and closed when the cock is open in another position, substantially as described.
